Sylvia North

NZ Registered Dietitian · PhD, metabolic health

A New Zealand Registered Dietitian who cuts through wellness noise with evidence and real food. Sylvia writes and reviews the health content on this site, so what you read holds up.

Sylvia North, NZ Registered Dietitian

Background

Evidence over wellness noise.

Sylvia is a New Zealand Registered Dietitian with a doctorate in metabolic health. She works on the things that quietly derail how people feel day to day: digestive problems and food intolerances, hormonal issues, stubborn weight, and low energy.

Her approach is built on real food and real-life strategy, not restriction or the latest trend. She treats every body as individual, and works out what actually moves someone toward their goals rather than handing over a generic plan.

She trained in the era of low-fat, calorie-counting dogma and watched the evidence move on. Staying current, and being honest about what the science does and doesn't show, is the whole point for her.

Her role at Biosphere

The nutrition claims answer to a dietitian.

Ron formulates the products. Sylvia makes sure the words around them are true. She writes and checks the health content on this site. She is also the scientific reviewer for astaxanthin.co.nz, an evidence guide to astaxanthin.

  • Writes the content

    The nutrition and health articles are authored with a dietitian's training, not lifted from a search result.

  • Checks the claims

    Health and nutrition claims are held against current evidence before anything is published.

  • Keeps it current

    Guidance reflects where the science actually is now, not where it sat twenty years ago.
